If I made a track out of some strong wire and ran a 9v current throug it could I propel something like the projectile in the 10 minute rail gun project down it?

You are suggesting replacing the aluminum foil track with a pair of wires.

How are you planning to keep the wheels on the wires?

If you attach a couple washers to each magnet, where the washers are slightly
larger than the magnet, you can make the wheels into pulleys that will stay on
the wire. The extra friction may be too much for the device, but it sounds
worth a try.

what if I put another pair of magnets under the first ones would that possibly hold them on?

You can try.
The wire is round, and the magnets should fall off as soon as it moved.
The washers make it stay on the same way railroad cars stay on the track.

Why not use something that is already flat, like aluminum foil?

Try it.
I think all of the most likely problems you might find are things you
are capable of fixing.
